-. PICK.

SPECIFICATION forming part of Letters Patent No. 524,819, dated August21, 1894.

Application filed December 28, 1892. Renewed June 20, 1894:. SerialNo-515,192. (No model.)

To all whom it may concern:

Be it known that I, JOHN Z. COBLENS, acitizen of the UnitedStates,-residing in the city of New York, in the county and State of NewYork, have invented certain new and useful Improvements in Picks, ofwhich the following 1s a specification.

This invention has reference to an improved pick of that class which isknown as eyeless picks, and more especially to picks for 11 ght'miningand other work in which not only a smaller size of pick-bar, but also ahandle socket of reduced Weight is required; and the invention consistsof a pick-bar, the handle-socket of which is formed of two edgepleceshaving openings for the middle-portion of the pick-bar, said edge-piecesbeing provided with abutments, that extend at right angles from theinner faces of the edgepieces, rivets passing through holes of the upperpart of the edge-pieces and the pick-bar and a screw-bolt that connectsthe lower ends of the edge-pieces with the handle, as will be fullydescribed hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1, represents a side-elevation ofmy improved pick. Fig. 2, is a vertical transverse section tion of thepick-bar.

of the same, on line 2 2, Fig. 1. Fig. 3, is a top-view of the same, andFig. 4, is a perspect1ve view of one of the edge-pieces, shown asdetached from the pick.

Similar letters of reference indicate col-re spending parts.

Referring to the drawings A represents an eyeless pick-bar or other toolwhich is used for light mining or other work, andwhich is made of aconsiderably smallersize than the ordinary pick-bars in use. Themiddle-port1on of the pick-bar is connected with the handle B by meansof two edgepieces 0 O which are provided at their upper ends withopenings that correspond in size with the middle portion of the pickbar,said openings fitting snugly to the pick and being provided at theirupper and lower interior faces with a slight inclination or bevel, sothat a biting action is exerted by the diagonally-opposite edges of thefaces on the middle por- The lower ends or 1 die.

shanks of the edge-pieces O C are provided with strengthening ribs andare attached to the handle D that is inserted between the same by meansof a fastening screw-bolt C that is passed through openings of the lowerend of the edge pieces 0 and through the handle, one end of thescrew-boltbeing provided with ahead, while the other end is providedwith ascreW-thread so as to engage the interiorly-threaded opening ofthe opposite edge-piece C, as shown clearly in Fig. 1, and dispensingthereby with a separate screw-nut for this purpose. Each edge-piece C isprovided with a laterally -projecting bracketshaped or abutment B ofangular cross-section, which abutments extend at right angles from theinner edges of the edge pieces across the handle, until they form contacwith each other at theirinner ends. i The inwardly-bent flanges of theabutments B form stops or rests against which the end of the handle Babuts. The upper ends of the edgepieces '0 C are fastened to thepick-bar by transverse rivets E which pass through holes of theedge-pieces and pick-bar.

The construction described forms a very strong and reliablehandle-socket for picks of small size, inasmuch as s only twoedgepieces, two rivets and one fastening-bolt are necessary to form astrong and reliable socket connection between the pick-bar and the han-At the same time the weight of the pickbar and its handle-socket isgreatly. diminished, so that the pick is better adapted for mining'andsimilar purposes for which a light and easily handled pick is required.

The combination, of a pick-bar, edgepieces havingopenings for the middle-portion of the pick bar and bracket shapedabutments projecting toward each other, rivets passing through holes ofthe edge-pieces and pick-bar, a handle, and a screw-bolt for conmeetingthe lower ends of the edge-pieces and pick-handle, substantially as setforth.
